Chapter 8 ­ Alkynes: Nomenclature Same general rules that we have seen before with alkanes and alkenes 1. Suffix ­yne 2. Triple bond receives the lowest possible number on the parent chain 3. If there is more than one triple bond in the parent chain, use di, tri, tetra, etc. ... 4. Compounds with double and triple bonds are called "­enynes" (not "­ynenes")

Unformatted text preview: 5. Numbering starts on the end of the chain closest to the first multiple bond ­ if there is a choice, alkenes take the lower number 6. Substituents that contain alkynes are called alkynyl groups Example: Title: Jul 12 ­ 9:49 AM (6 of 9) Preparation of Alkynes: EliminationReactions of Dihalides Mechanism: Title: Jul 13 ­ 9:36 AM (7 of 9) Reaction of Alkynes: Addition of HX and X 2 Example: Mechanism: Title: Jul 13 ­ 9:46 AM (8 of 9) Halogenation: Hydration of Alkynes: Two Methods 1. Mercury (II) ­ Catalyzed Hydration of Alkynes enol = vinylic alcohol (alkene + alcohol) enols immediately rearrange to form the more stable keto tautomer Tautomers: constitutional isomers that rapidly interconvert Title: Jul 13 ­ 9:48 AM (9 of 9)...
